What Is A Breathalyzer?
A breathalyzer is a device used for estimating the blood alcohol level (BAL) from a breath sample. This device is equipped with sensors that measure the subject’s BAL and provide accurate readings. The device has a tube-like structure, which you breathe into, and a chamber for the electrochemical process. Here, the alcohol is oxidized, and an electrical current is produced. This detects the concentration of alcohol in your system. There are three main types of breathalyzers available. Take a look.
Types Of Breathalyzers
1. Semiconductor Oxide-Based Testers
These are relatively new, affordable, and simple devices. They use ethanol sensors to measure the subject’s blood alcohol content. The devices are equipped with a semiconductor that reacts with alcohol and changes the electrochemical current. The larger the change, the larger the alcohol content. These devices are for personal, home, or non-professional testing.
2. Fuel Cell Sensors
These are professional breathalyzers that provide accurate readings. Most officers use a fuel cell breathalyzer for roadside screenings. This device measures alcohol content by creating an electrochemical reaction that oxidizes alcohol and produces an electrical current. The greater the current, the higher the alcohol content. The current is then measured to determine the BAC readings. Fuel cell sensors are made with expensive materials like platinum electrodes that help oxidize the alcohol to produce protons and electrons.
3. Infrared Spectrometer
These are used in table-top breathalyzers by traffic officials or at police stations. They identify the molecules within the sample of air and measure the amount of infrared light absorbed by them. Since ethanol can only absorb a certain wavelength of infrared radiation, the more the wavelength absorbed, the more the alcohol content. These devices provide 1005 accurate BAC readings. Now that we know the types let’s take a look at the top 10 breathalyzers you can buy.

What To Look For In A Breathalyzer
These are the key considerations that you need to keep in mind while buying a breathalyzer:
Accuracy
Before purchasing a breathalyzer, you should know that these devices are not 100% accurate, but some are very close. If you are looking for accurate readings, some breathalyzers have a marginal error of ±0.001. This is the maximum margin allowed by the law. However, some devices claim to be 100% accurate, which is not true.
Calibration
Whether you use the breathalyzer more than once a day or less than once every 2 to 3 months, you need to send your device for calibration. Though the need for frequent calibration is very less for personal use breathalyzer, it will be beneficial to send it away for calibration at least once a year.
Legally Approved
It is important that you choose a breathalyzer that is approved by the DOT, NHTSA, FDA, and other similar government bodies, depending on your country. This is so that these devices are accurate and match the police readings.
Technology
Most accurate breathalyzers use fuel cell technology. Other devices with not-so-accurate functioning use semiconductor sensors.
Replaceable Mouthpiece
Look for a device that comes with a replaceable mouthpiece for accurate results. Some devices provide disposable mouthpieces for hygiene and accuracy purposes. Uncontrolled drinking is dangerous for you and your peers, as well. Get these handy gadgets and stay sober and safe.

Why Trust StyleCraze?
The author has compiled a list of the best breathalyzers after carefully considering several online reviews and general feedback from worldwide users. Each product has also been closely reviewed, keeping in mind factors such as accuracy, calibration, and legal approval. These health devices prove extremely handy in monitoring blood alcohol levels that determine if you are fit enough to get behind the wheels. How accurate are breathalyzers? High-quality breathalyzers have only 0.001% chance of error. They accurately determine the amount of alcohol concentration in your system. What is a normal breathalyzer reading? A reading of 0.05% BAC or less is a standard breathalyzer reading. It is a legal alcohol limit to drive. Can drinking water help you pass a breathalyzer? No. Drinking water or hyperventilation does not impact the alcohol level in your system. How long do you have to breathe in a breathalyzer? Breathe in a breathalyzer for approximately four to five seconds to record the BAC level. Does smoking affect a breathalyzer test? Yes. A smoker contains more acetaldehyde in their system that reflects on a breathalyzer test, even if the person has not consumed alcohol. Can coffee set off a breathalyzer? No. Coffee does not increase the BAC level in your system. It does not affect alcohol concentration. Can a breathalyzer detect Coke? No. Breathalyzers can not detect the presence of coke in your system. Recommended Articles:
